remove useless code recently added to RouteGroup

When a slaved automation control is changed because of a Master changing
its own value, the slave notifies about the change with NoGroup as the
GroupControlDisposition. There is therefore no need to disable a RouteGroup's
enabled status for its ControlGroups - the changes initiated by any Master
will not propagate to the group (which is precisely what we intend)
